Brief Title: Immunological Response to Intravesical BCG Therapy of Superficial Bladder Cancer by Prior Administration of RUTI®

A Randomized, Double-Blind, Placebo-Controlled Phase I Trial to Evaluate the Immunomodulatory Effect of RUTI® in Individuals With High-Risk Non-Muscle-Invasive Bladder Cancer (NMIBC) Treated With Intravesical Bacillus Calmette-Guerin (BCG)

INTRODUCTION

  • Org Study ID: RUTIVAC-1
  • Secondary ID: N/A
  • NTC ID: NCT03191578
  • Sponsor: Archivel Farma S.L.

BRIEF SUMMARY

The RUTIVAC-1 study is a Phase I Clinical Trial designed to evaluate the systemic and mucosal immunological response and provide safety information after the use of RUTI® administration to individuals with NMIBC.

The study will enroll individuals treated with Transurethral resection of bladder tumor (TURBT), diagnosed to have high-risk Non-muscle invasive bladder cancer (NMIBC) and suitable candidates for BCG therapy and who meet all eligibility criteria.

Forty individuals will be recruited and randomized 1:1 to receive two subcutaneous shots of 25 μg RUTI® or placebo. After vaccination, individuals will receive the standard induction course, of intravesical Bacillus Calmette-Guerin (BCG)therapy (weekly BCG for six weeks).

4 to 8 weeks after the last intravesical BCG administration (BCG6) a visit will be performed (Visit 1, end of the interventional phase). Once all participants have performed VISIT 1 immunological assays will be performed and data will be analyzed.

At the end of the Interventional Phase the blind will be opened, except for the study physicians who will remain blind during all the follow-up. All the individuals will be followed up for three years since TURBT.

ELIGIBILITY

Inclusion Criteria:
Written ICF for participation in the study.

- Age ≥18 years.

- General health status according to WHO ≤ 2.

- Have primary histologically confirmed T1 and/or high grade tumors and/or CIS.

- All visible papillary tumors must be completely resected.
